Bugfix 1

Dear (mini) Breeze community,

i have adressed some issues that were pointed out by dev-vaayen, including:

- Guide has been upgraded.

- Camera rotation velocity now takes FPS into account.

- Levels are now sequentially unlocked as the user passes the missions.

- The third map (missions 5 and 6) has been fixed.

- You can now use the key "T" to cheat and gain altitude.

Sadly there is a problem with the cloud shader, which seems to be too complicated for WebGL integration. This will be the next fix in the following days. I'm still looking for collaborations, tips and ideas.

Happy playing!
